Method for preventing and curing pests and diseases of ginger
? ?At present, the price of ginger is falling, and many ginger farmers are unwilling to sell it and start to choose to store ginger. However, according to the experience of previous years, ginger has many diseases and insect pests during storage. If it is not controlled in time, it will cause considerable losses.
Plague disease is an important disease of ginger in storage. It is an infectious disease during storage. Once the conditions are suitable during storage, the infection spreads. The diseased ginger block is dull and dull, with a black heart or black shape incision. The darker the color, the heavier the disease. Control methods: After harvesting, they should be exposed to the sun for 1 to 2 days to kill germs and dry the epidermis. Let the ginger evaporate more water to prevent it from heating and rotting due to excessive moisture entering the cellar. During storage, you should check at any time to find out that the blast is cleaned up in time to avoid infection. Strictly remove diseased ginger before storage.
Black mold or rotten skin appears on the surface of ginger, especially when tubers are injured and the environment is suitable. Control methods: Disinfection of storage pits in advance. At present, the commonly used disinfection methods are two methods, namely, smoking and applying a certain amount of quicklime in the cellar, which are simple and easy to implement and have good results.
Ascaris lumbricoides are mainly heteromorphic eye mosquitoes, which are the main pests of ginger during storage. The investigation found that, due to the rush of the farmers when harvesting ginger, part of the soil on the surface of the ginger block may carry heteromorphic mosquitoes. In addition, the way ginger is put into the cellar is backward, and the way to store ginger is simple, which makes the occurrence of heteromorphic eye mushrooms in the well cellar more serious. In the well cellar, because its perennial temperature is between 15 ° C and 20 ° C, it is suitable for the occurrence of heteromorphic eye fly mosquitoes, and its larvae bite the ginger block, which will cause the affected part to rot and lose its commercial value.
For the prevention and treatment of eye mosquitoes, the first step is to find and eradicate the plants damaged by alien eye mosquitoes in the field in time to avoid bringing them into the well cellar during harvesting. Second, do well cleaning and spray disinfection of the well cellar in advance. It can be mixed with 15 kg of water with 1.8% avermectin EC and sprayed evenly on the fine sand and walls in the well cellar. Also pay attention to the arrangement of ginger cubes into the cellar. A layer of ginger and a layer of fine sand is appropriate. Thirdly, after the ginger pieces are put into the cellar, the mouth of the cellar should be sealed to prevent the adults from flying into the spawning.
